hide measures

[paullee]

I find Wmayer says ' Implemented in 0.17 ' in 1/2017.

I am confused - should I reported by adding to the same bug/feature report?
(otherwise I may confuse the bug tracker )

There was an implementation to hide the blue constraints but then there was an (unsolvealble?) bug.

Thanks, glad and sorry to hear that

I do not see any thing about that in the bug/feature tracker? Need to do something to report?

Thanks for pointing out the discussion!

I see your videos, one on Sketch Proxy and another on Sketcher::SketchObjectPython.

I am working on an idea to have DistXY reference constraints on a sketch, and cross-referencing those reference constraints in anther by expression engine - with very limited knowledge in FC, python etc. here. https://forum.freecadweb.org/viewtopic.php?f=3&t=24570. Manually input the expression engine from 1 sketch to another (your 'driven' and 'driver'), still working on a script to see if i can select the 'driven' and the 'driver' so that the expression could be input. Good to learn from your script also!

The Sketch Proxy seem purely on expression engine right? The latter I have no knowledge to understand the *.py at the moment.

BTW, on the Sketcher 'mini'-features, i hope the Geometry which are construction could be hidden also, in addition to 'Reference / Driven' 'Constraints'.

Thanks anyway.

At the moment I work on "feedback sketches".
The idea is:
one sketch reads data from another (I do not use external geometry and no expression do be more flexible)
then it is solved and sends back the data to the origin or other sketches.

this way I can split complexity and can reduce the user interface to some simple to mantain sketches.
the main problems are:
avoid deadlocks and avoid recursive recomputes.

I found some tricks to do this in python.
we will use it first here: https://forum.freecadweb.org/viewtopic. ... 80#p193413

I watched that video, impressive. Do you mind sharing the files? - though I may be far from understanding.

I am avoiding external geometry in favour of expression, for the former is volatile not surviving any underlying changes (should be banned?)
